Anne Calthorpe

Anne Calthorpe, Countess of Sussex (died between 22 August 1579 and 28 March 1582) was the second wife of Henry Radcliffe, 2nd Earl of Sussex, who divorced her in 1555 on the grounds of her alleged bigamous marriage to Sir Edmund Knyvet, and her "unnatural and unkind" character.

She served as a lady-in-waiting in the household of Queen consort Catherine Parr, the sixth wife of King Henry VIII, and shared her Reformed beliefs. She was implicated in the heresy of Anne Askew. In 1552, she was sent to the Tower of London for having practised sorcery and having made "treasonous prophecies".

Anne was the daughter of Sir Philip Calthorpe of Burnham Thorpe, Norfolk and his second wife, Jane Blennerhassett. Anne had an older half-brother Sir Philip Calthorpe who married Jane Boleyn, paternal aunt of Queen Anne Boleyn.

Sometime before 21 November 1538, she married as his second wife, Henry Radcliffe, heir to the earldom of Sussex, whose wife, Elizabeth Howard had died in 1537. He was a second cousin of King Henry VIII of England as they shared Richard Woodville, 1st Earl Rivers and Jacquetta of Luxembourg as great-grandparents.

Together Henry and Anne had three children:

Anne had two stepsons, Thomas and Henry from her husband's first marriage.
